TECHNICAL BACKGROUND

Transforming growth factor beta (TGF-beta), a multifunctional growth factor that for example controls proliferation or cellular differentiation, is one of the most important ligands involved in the regulation of cell behavior in ocular tissues in physiological or pathological processes of development or tissue repair, although various other growth factors are also involved. Increased activity of this ligand may induce unfavorable inflammatory responses and tissue fibrosis. In mammals, three isoforms of TGF-beta, that is beta1, beta2, and beta3, are known. In most cases, TGF-beta enhances extracellular matrix production and suppresses cell proliferation. Moreover, TGF-beta is capable of inducing a number of growth factors, that is connective tissue growth factor (CTGF), platelet-derived growth factor (PDGF), fibroblast growth factors (FGFs), and vascular endothelial growth factor (VEGF), as well as TGF-beta1 itself. All these factors have important roles in restoration of normal tissue following injury.

The aqueous humor that bathes the inner ocular structures (corneal endothelium, iris, crystalline lens, trabecular meshwork, and retina) contains various cytokines and growth factors. TGF-beta, in particular TGF-beta2, is the predominant cytokine. Physiologically, TGF-beta is mainly produced in the ciliary epithelium and lens epithelium as a latent, inactive, form consisting of mature TGF-beta, the latency-associated peptide (LAP) (small latent form), and the latent-TGF-beta-binding protein (LTBP). Heterogeneous expression patterns of each TGF-beta isoform in the crystalline lens have been reported in humans and animals. During the clinical course of various ocular diseases, the concentration of TGF-beta2 in the aqueous humor changes. For example, in an eye with proliferative vitreoretinopathy (PVR), a disorder of post-retinal detachment and retinal fibrosis, the concentration of TGF-beta2 in the vitreous humor increases in association with the progression of retinal fibrosis. The concentration of total and active TGF-beta2 is also higher in patients with diabetic retinopathy and open-angle glaucoma than in normal subjects. In diabetic retinopathy, chronic obstruction of retinal microvessels induces upregulation of VEGF and chemotaxis of macrophages, a potent source of TGF-beta. VEGF and TGF-beta cooperate to induce both retinal neovascularization and fibrosis around these new vessels, which may potentially cause retinal detachment or bleeding. Increased TGF-beta2 levels induce matrix expression and deposition in trabecular meshwork cells, leading to obstruction of the aqueous drainage route and an increase of intraocular pressure in a glaucomatous eye. In each of these examples, TGF-beta plays a role in disease pathogenesis. In eyes with pseudoexforiation syndrome, a kind of glaucoma with deposition of exforiative material on the lens, iris, or trabecular meshwork, the level of TGF-beta1 increases, but the exact role of TGF-beta1 in the pathogenesis of this disease is unknown (see Shizuya Saika, Laborartory Investigation (2006), 86, 106-115).

TGF-beta is one of the most potent regulators of the production and deposition of extracellular matrix. It stimulates the production and affects the adhesive properties of the extracellular matrix by two major mechanisms. First, TGF-beta stimulates fibroblasts and other cells to produce extracellular-matrix proteins and cell-adhesion proteins, including collagen, fibronectin, and integrins. Second, TGF-beta decreases the production of enzymes that degrade the extracellular matrix, including collagenase, heparinase, and stromelysin, and increases the production of proteins that inhibit enzymes that degrade the extracellular matrix, including plasminogen-activator inhibitor type 1 and tissue inhibitor of metalloprotease. The net effect of these changes is to increase the production of extracellular-matrix proteins and either to increase or to decrease the adhesive properties of cells in a cell-specific manner (see Blobe G C et al., May 2000, “Role of transforming growth factor beta in human disease”, N. Engl. J. Med. 342 (18), 1350-1358).

Targeting TGF-beta has been proposed as a potential therapeutic measure for example in glaucoma. Concerning various aspects of TGF-beta in the pathogenesis of glaucoma, therapies should be directed to modulate its production, activation, interaction with receptors, downstream intracellular regulatory mechanisms and/or the final structural and ECM changes (see Prendes M A et al., Br J Ophthalmol (2013), 97, 680-686).

Glaucoma (GCM), based upon chronically increased intraocular pressure, is a progressive optic neuropathy characterized by progressive loss of retinal ganglion cells, which manifests clinically with loss of optic disc neuroretinal rim tissue, defects in the retinal nerve fiber layer, and deficits on functional visual field testing (see Danesh-Meyer et al., Ophthalmol. 2006, 113: 603-611). Glaucoma is the second leading cause for blindness in the adult in the USA. Despite a multitude of treatment options, including surgical procedures in referactory patients, blindness remains a major threat. Primary open-angle glaucoma (POAG) is the most common form of glaucoma in the USA. Worldwide, in the year 2000 the number of people with POAG has been estimated at nearly 66.8 million with 6.7 million having bilateral blindness (see Quingley, Br J Ophthalmol. 1996 May; 80(5):389-393).

Cataract surgery is the most common ophthalmic surgical procedure. Alone in the USA, up to 3.000.000 cataract surgeries are performed per year. The US government spends currently more than USD 3 billion per year on treating cataract (Medicare patients only). The lens of the eye is removed by the procedure, and an intraocular lens is implanted. The lens capsule remains in situ, and the posterior part of the capsule frequently develops posterior capsule opacification (PCO) due to mechanical disruption and potential other factors associated with lens replacement. This condition occurs in 20 to 40% of PCO patients, YAG-laser posterior capsulotomy (rates depend on country, lens type used and surgical experience) is performed within the first two years, to remove the opacification (see Johansson B et al., Br J Ophthalmol (2010), 94, 450-455; Mathew R G et al., Ophthalmic Surg Lasers Imaging (2010), 41, 651-655). The use of the YAG-laser is associated with distince risks, including retinal detachment (1-3%), cystoid macular oedema (up to 5%) and secondary glaucoma (see Billotte C and Berdeaux G, J Cataract Refract Surg (2004), 30(10), 2064-2071).

TGF-beta has been closely associated with the pathophysiology of both, GCM and PCO; so far, the effect of the TGF-beta protein has been inhibited by ALKS inhibitors as for example described in WO 2009/146408 or antibodies directed to TGF-beta, i.e., one of its isoforms, which are disclosed for example in WO 2012/167143. None of these compounds has so far been successful in effective inhibiting TGF-beta in the eye, and thus, to be successful in the prevention and/or treatment of ophthalmic diseases such as GCM or PCO.

It is the objective of the present invention to provide an oligonucleotide, preferably an antisense oligonucleotide, which is specifically inhibiting the expression of TGF-beta1, TGF-beta2, and/or TGF-beta3 mRNA, TGF-beta1 and TGF-beta2 mRNA, or TGF-beta1 and TGF-beta3 mRNA, or TGF-beta2 and TGF-beta3 mRNA, and consequently is highly efficient for use in prevention and/or treatment of an ophthalmic disease without causing any (severe) side effects.

Further preferred oligonucleotides of the present invention are ASPH1000 to ASPH1132 as shown in Table 1, which preferably inhibit the expression and/or activity of TGFbeta1 mRNA. Preferred oligonucleotides this group are for example ASPH1047, ASPH1051, ASPH1059, ASPH1106, ASPH1139, ASPH1150, ASPH1162, ASPH1163, ASPH1175, ASPH1178, and ASPH1181, respectively.

In an alternative embodiment oligonucleotides are preferably inhibiting the expression and/or activity of TGF-beta3 mRNA. Such oligonucleotides are for example ASPH2000, ASPH2001, ASPH2002, ASPH2003, ASPH2004, ASPH2005, ASPH2006, ASPH2007, ASPH2008, ASPH2009, ASPH2010, ASPH2011, ASPH2012, ASPH2013, ASPH2014, ASPH2015, ASPH2016, ASPH2017, ASPH2018, ASPH2019, ASPH2020, ASPH2021, ASPH2022, ASPH2023, ASPH2024, ASPH2025, ASPH2026, ASPH2027, ASPH2028, ASPH2029, ASPH2030, ASPH2031, ASPH2032, ASPH2033, ASPH2034, ASPH2035, ASPH2036, ASPH2037, ASPH2038, ASPH2039, ASPH2040, ASPH2041, ASPH2042, ASPH2043, ASPH2044, ASPH2045, ASPH2046, ASPH2047, ASPH2048, ASPH2049, ASPH2050, ASPH2051, ASPH2052, ASPH2053, ASPH2054, ASPH2055, ASPH2056, ASPH2057, ASPH2058, ASPH2059, ASPH2060, ASPH2061, ASPH2062, ASPH2063, ASPH2064, ASPH2065, and ASPH2066, respectively.

Oligonucleotides of the present invention show an unexpected strong and specific inhibition of TGF-beta1, TGF-beta2, or TGF-beta3, or TGF-beta1 and TGF-beta2. Alternatively, oligonucleotides of the present invention show strong and specific inhibition of TGF-beta1 and TGF-beta3, or TGF-beta1 and TGF-beta2, or TGF-beta2 and TGF-beta3, and in a further alternative TGF-beta1, TGF-beta2 and TGF-beta3.

Modifications of one or more nucleotides of the oligonucleotides of the present invention are selected from the group consisting of LNA, ENA, polyalkylene oxide such as triethylene glycol (TEG), 2′-fluoro, 2′-O-methoxy and 2′-O-methyl. The modifications are preferably located at the 5′- and/or 3′-end of the oligonucleotide. An oligonucleotide comprising such modified nucleotide is a modified oligonucleotide.

Modified nucleotides are for example arranged in a row, one directly next to the other, or in different patterns, where one or more unmodified nucleotides follow a modified nucleotide. For example an oligonucleotide starts with one or more modified nucleotides followed by one or more, e.g., one, two, three or four, unmodified or unlocked nucleotides followed again by one or more modified nucleotides. In one embodiment both ends of the oligonucleotide comprise an identical pattern of modified and unmodified or unlocked nucleotides. In another embodiment, the pattern of modifications at the 3′- and 5′-end differ including that one end does not comprise a modified nucleotide. Preferably the modified oligonucleotides comprise a series of 8 or 9 unlocked nucleotides.

Alternatively, a nucleotide at any other position in the oligonucleotide is modified, or at least one nucleotide at the 5′- and/or 3′-end of the oligonucleotide and at any other position in the oligonucleotide. For example ASPH1071, ASPH1100, ASPH1109, ASPH 1110, ASPH1111, ASPH1115, ASPH1126, ASPH1127 and ASPH1128 belong to a group of TGF-beta oligonucleotides, for example TGF-beta1 oligonucleotides, which comprises modified nucleosides such as LNA, ENA etc. in different patterns, e.g., separated from each other by an unlocked nucleotide. The oligonucleotides comprise either one type of modification, or one or more different modifications. Optionally, at least one phosphate linkage between two consecutive nucleotides (modified or unmodified) of the oligonucleotide is a phosphorothioate or a methylphosphonate. In a preferred embodiment, the oligonucleotides of the present invention are phosphorothioates.

Moreover, the present invention refers to TGF-beta antisense oligonucleotides, which interact and inhibit the expression of more than one TGF-beta isoform, even if the oligonucleotide is not 100% complementary to the TGF-beta1, TGF-beta2 and/or TGF-beta3 sequence. Such antisense oligonucleotides are for example ASPH1024, ASPH1096, ASPH1131 and ASPH1132, respectively. These oligonucleotides preferably interact with TGF-beta sequences of the same or different species such as human, monkey, rat or mouse as for example ASPH1131 and ASPH1132, respectively.

All the oligonucleotides of the different embodiments are for use in a method of the prevention and/or treatment of an ophthalmic disease such as dry eye, glaucoma, posterior capsular opacification (PCO), retinoblastoma, choroidcarcinoma, Marfan or Loeys-Dietz syndrome, macular degeneration, such as age-related macular degeneration, diabetic macular endma, or cataract.

A nucleotide forms the building block of an oligonucleotide, and is for example composed of a nucleobase (nitrogenous base, e.g., purine or pyrimidine), a five-carbon sugar (e.g., ribose, 2-deoxyribose, arabinose, xylose, lyxose, allose, altorse, glucose, mannose, gulose, idose, galactose, talose or stabilized modifications of those sugars), and one or more phosphate groups. Examples of modified phosphate groups are phosphorothioate or methylphosphonate. Each compound of the nucleotide is modifiable, and is naturally occurring or none naturally occurring. The latter are for example locked nucleic acid (LNA), a 2′-0,4′-C-ethylene-bridged nucleic acid (ENA), polyalkylene oxide- (such as triethylene glycol (TEG)), 2′-fluoro, 2′-O-methoxy and 2′-O-methyl modified nucleotides as described for example by Freier & Altmann (Nucl. Acid Res., 1997, 25, 4429-4443) and Uhlmann (Curr. Opinion in Drug & Development (2000, 3 (2): 293-213)), which are shown in FIG. 4.

A LNA is a modified RNA nucleotide, wherein the ribose moiety is modified with an extra bridge connecting the 2′ oxygen and 4′ carbon (2′-4′ribonucleoside). The bridge “locks” the ribose in the 3′-endo (North) conformation, which is often found in the A-form duplexes. LNA nucleosides and nucleotides, respectively, comprise for example the forms of thio-LNA, oxy-LNA, or amino-LNA, in alpha-D- or beta-L-configuration, and are mixable and combineable, respectively, with (unmodified) DNA or RNA residues in the oligonucleotide.

The oligonucleotides of the present invention, i.e., modified oligonucleotides, comprise at least one modified nucleotide, preferably LNA and/or ENA, at the 5′- and/or 3′-end of the oligonucleotide. In a preferred embodiment, the oligonucleotide comprises 1, 2, 3, or 4 LNAs or ENAs at the 5′-end, and 1, 2, 3, or 4 LNAs or ENAs at the 3′-end. In another preferred embodiment, the oligonucleotide comprises 1, 2, 3, or 4 LNAs or ENAs at the 5′-end or 3′-end, and a polyalkylene oxide such as TEG at the 3′- or 5′-end. The modified oligonucleotides show a significantly increased inhibition on TGF-beta expression and activity, respectively, which results in an improved prevention and/or treatment of a malignant or benign tumor, an immunologic disease, fibrosis, eye disease such as glaucoma or posterior capsular opacification (PCO), CNS disease hair loss etc. The oligonucleotides of the present invention target TGF-beta linked diseases either by hybridization with TGF-beta mRNA, preferably TGF-beta1, TGF-beta2, or TGF-beta3, alternatively, TGF-beta1, TGF-beta2, and/or TGF-beta3 mRNAs, i.e., TGF-beta1 and TGF-beta2, or TGF-beta1 and TGF-beta3, or TGF-beta2 and TGF-beta3, or TGF-beta1, TGF-beta2 and TGF-beta3 mRNAs, or any other direct or indirect effect on the TGF-beta system. An oligonucleotide inhibiting the expression of TGF-beta1, TGF-beta2, and TGF-beta3 is defined as pan-specific oligonucleotide.

In a preferred embodiment, the oligonucleotides of the present invention are for use in a method for preventing and/or treating an ophthalmic disease such as dry eye, glaucoma or posterior capsule opacification.

Preferably two or more oligonucleotides are combined, wherein at least one oligonucleotide specifically inhibits TGF-beta1 and at least one oligonucleotide specifically inhibits TGF-beta2, or wherein at least one oligonucleotide specifically inhibits TGF-beta1 and at least one oligonucleotide specifically inhibits TGF-beta3, or wherein at least one oligonucleotide specifically inhibits TGF-beta2 and at least one oligonucleotide specifically inhibits TGF-beta3, or wherein at least one oligonucleotide specifically inhibits TGF-beta1, at least one oligonucleotide specifically inhibits TGF-beta2, and at least one oligonucleotide specifically inhibits TGF-beta3.

In another embodiment, one oligonucleotide inhibits two TGF-beta isoforms such as TGF-beta1 and TGF-beta2, TGF-beta2 and TGF-beta3, or TGF-beta1 and TGF-beta3. An oligonucleotide inhibiting the expression of all three isoforms—TGF-beta1, TGF-beta2, and TGF-beta3—is defined as pan-specific oligonucleotide.

In a further embodiment three or more oligonucleotides are combined, wherein at least one oligonucleotide specifically inhibits TGF-beta1, another oligonucleotide specifically inhibits TGF-beta2, and a further oligonucleotide specifically inhibits TGF-beta3, and optionally one or more additional oligonucleotides inhibiting TGF-beta1, TGF-beta2 or TGF-beta3, and/or optionally any other factor.

The description of the modifications in Table 2 corresponds to the description provided in Table 1; in addition, LNA nucleosides are indicated in the sequence in bold letters, and triethylene glycol is abbreviated as TEG in Table 2.

For the purpose of clarity and a concise description, features are described herein as part of the same or separate embodiments, however, it will be appreciated that the scope of the invention may include embodiments having combinations of all or some of the features described.

The following examples will serve to further illustrate the present invention without, at the same time, however, constituting any limitation thereof. On the contrary, it is to be clearly understood that the scope of the present invention refers to various other embodiments, modifications, and equivalents thereof which, after reading the description herein, may suggest themselves to those skilled in the art without departing from the spirit of the invention.

EXAMPLES

In the following examples, the effect of the oligonucleotides listed in Tables 1 and 2 have been tested in view of the reduction and inhibition, respectively, of TGF-beta1 and/or TGF-beta2 expression. SEQ ID NO. 144 (T-LNA: CGGCATGTCTATTTTGTA, wherein 3×nucleotides at the 5′- and 3′-end are LNAs) and SEQ ID NO. 145 (scr-LNA: CGTTTAGGCTATGTACTT, wherein 3×nucleotides at the 5′- and 3′-end are LNAs) are used as control oligonucleotides, wherein SEQ ID NO. 145 (negative control) is the scrambled form of SEQ ID NO. 144 (positive control). The cells were either transfected in the presence of a transfecting agent (e.g., Lipofectamine), or in the absence of any transfecting agent (gymnotic transfection or unassisted transfection or gymnotic delivery). As in case of a gymnotic transfection the entry of the oligonucleotide into the cell solely depends on the interaction of the oligonucleotide and the cell, and no compound supports the entry, gymnotic transfection reflects better conditions of the in vivo experimental settings.

The dual TGF-beta1 and TGF-beta2 reactive oligonucleotides ASPH01, ASPH02, ASPH03, ASPH04, ASPH05, ASPH06, ASPH07, and ASPH08 show again a significant reduction of the expression of both TGF-beta1 and TGF-beta2 mRNA, while the selective TGF-beta2 oligonucleotides significantly inhibit TGF-beta2 mRNA expression.

Example 3

In further experiments the inhibitory effect of ASPH01, ASPH03, ASPH05, ASPH17, ASPH18, ASPH22, ASPH26, ASPH27, ASPH33, ASPH36, ASPH37, ASPH41, ASPH42, ASPH45, ASPH46, ASPH47, ASPH48, ASPH49, ASPH64, ASPH65, ASPH66, ASPH69, ASPH71, ASPH80, ASPH82, ASPH88, ASPH89, ASPH90, ASPH98, ASPH99, ASPH102, ASPH105, ASPH115, ASPH121, ASPH140, ASPH153, ASPH165, ASPH171, ASPH178, ASPH181, ASPH184, ASPH185, ASPH186, ASPH187, ASPH188, ASPH189, and of the controls of SEQ ID NO.144 and SEQ ID NO. 145, respectively, was tested in A172 cells. A172 cells were transfected with these modified oligonucleotides in doses of 20 nM, 4 nM, 0.8 nM, 0.16 nM, and 0.04 nM, respectively, in the presence of a transfecting agent. The remaining TGF-beta2 mRNA was measured 24 h after transfection. TGF-beta2 values were normalized to GAPDH and oligonucleotide concentrations resulting in 50% reduction of TGF-beta2 mRNA (=IC₅₀ values) were calculated. All IC₅₀ values were referenced to the IC₅₀ value of ASPH_036 (ASPH36) that was 0.33 nM and the results are shown as fold-difference of the IC₅₀ value of ASPH_036 Table 3:

All the modified oligonucleotides show an IC₅₀ in a low nanomolar to picomolar range, which is markedly lower than IC₅₀ to the control oligonucleotide of SEQ ID NO. 144; the IC₅₀ of the control of SEQ ID NO. 145 was not calculable.

Example 4

Panc-1 cells were treated with 3.3 μM of each of ASPH17, ASPH18, ASPH22, ASPH25, ASPH33, ASPH35, ASPH36, ASPH41, ASPH42, ASPH45, ASPH46, ASPH47, ASPH48, ASPH49, ASPH65, ASPH66, ASPH67, ASPH69, ASPH71, ASPH79, ASPH80, ASPH82, ASPH88, ASPH89, ASPH90, ASPH91, ASPH98, ASPH99, ASPH102, ASPH105, ASPH111, ASPH115, ASPH119, ASPH121, ASPH139, ASPH140, ASPH146, ASPH151, ASPH153, ASPH165, ASPH171, ASPH172, ASPH176, ASPH178, ASPH180, and ASPH183, or the controls of SEQ ID NO. 144 and 145, respectively, in the absence of a transfecting agent (gymnotic transfection). The inhibitory effect of the modified oligonucleotides on expression of TGF-beta1 and TGF-beta2 mRNA, respectively, was determined 72 h after treatment start. Under gymnotic transfection experimental conditions, the oligonucleotides enter the cells and strongly inhibit the expression of TGF-beta2 mRNA. The results of the experiments are shown in FIG. 7(a) and FIG. 7(b).

Example 5

In further experiments Panc-1 cells were transfected with 10 μM of modified oligonucleotides ASPH01, ASPH03, ASPH05, ASPH09, ASPH17, ASPH18, ASPH22, ASPH35, ASPH36, ASPH37, ASPH41, ASPH45, ASPH46, ASPH47, and ASPH48, or the controls of SEQ ID NO. 144 and 145, respectively, in the absence of a transfecting agent (gymnotic transfection or gymnotic delivery). The oligonucleotides were added to the cells for 2 days, after which oligonucleotide containing incubation medium was changed, and further incubation for 2 days was carried out. Expression of TGF-beta1 mRNA (see FIG. 8a ) and TGF-beta2 mRNA (see FIG. 8b ) was then measured and normalized to HPRT1 (Hypoxanthin-Phosphoribosyl-Transferase1). Cell supernatants were analysed for TGF-beta1 (see FIG. 9a ) and TGF-beta2 (see FIG. 9b ) protein by ELISA. Under gymnotic delivery experimental conditions, the double reactive oligonucleotides ASPH01, ASPH03, ASPH05, and ASPH09 significantly inhibit the expression of TGF-beta1 and TGF-beta2 on mRNA, and likewise on the protein level. All the other oligonucleotides significantly inhibit the expression of TGF-beta2 on mRNA and protein level.

Example 6

In another experiment dose dependency of the inhibitory effect of modified oligonucleotides of the present invention was tested. Panc-1 cells were treated with 15 μM, 10 μM, 7.5 μM, 5 μM, 2.5 μM, 1.25 μM, or 0.625 μM ASPH05 or ASPH36, or the controls of SEQ ID NO. 144 and 145, respectively, without using a transfection reagent. The oligonucleotides were added to the cells for 2 days. Thereafter the incubation media containing the oligonucleotides were changed and cells were incubated for 2 further days. Thereafter (total treatment time: 4 days) the expression of TGF-beta1 (see FIG. 10a ) and TGF-beta2 (see FIG. 10b ) mRNA depending on the oligonucleotide concentration was measured. The dual TGF-beta1 and TGF-beta2 reactive oligonucleotide ASPH05 shows a marked dose dependent inhibition of both TGF-beta1 and TGF-beta2 mRNA expressions, and ASPH36 inhibits specifically the expression of TGF-beta2 mRNA in a dose-dependent manner.

Example 7

Mouse SMA-560 glioma cells were transfected with 10 nM ASPH01, ASPH03, ASPH05, ASPH09, ASPH17, ASPH18, ASPH22, ASPH26, ASPH36, ASPH37, ASPH41, ASPH42, ASPH45, ASPH46, ASPH47, or ASPH48, or the controls of SEQ ID NO. 144 and 145, respectively, in the presence of a transfecting agent. 24 h after transfection, the inhibition of the expression of TGF-beta1 (white columns) and TGF-beta2 (black columns) mRNA was determined. The dual TGF-beta1 and TGF-beta2 reactive oligonucleotide ASPH09 inhibits the expression of the mouse TGF-beta1 mRNA, and the other oligonucleotides tested strongly inhibit the expression of the mouse TGF-beta2 mRNA. The results are presented in FIG. 11.

Example 8

Female athymic nude mice (Hsd:Athymic Nude-Foxn1^(nu)) were treated for 5 consecutive days with 14 mg/kg or 50 mg/kg of oligonucleotide ASPH01, ASPH03, ASPH05, ASPH17, ASPH22, ASPH37, ASPH41, ASPH45, ASPH46, ASPH47, or ASPH48, and control of SEQ ID NO. 145 or saline by subcutaneous injection. The day after the last treatment, the mice were sacrificed. Mouse TGF-beta2 mRNA was quantified in kidney tissue lysates. In FIG. 12, data—representing TGF-beta2 to GAPDH mRNA ratio—are shown as a box plot in which median values and min. and max. values are presented (data expressed as n=4, except ASPH46 group n=3). All the tested oligonucleotides inhibited the expression of TGF-beta2 mRNA in the kidney of these mice.

Example 9

In another experiments Panc-1 cells were transfected with 10 μM of modified oligonucleotide ASPH09 or the control of SEQ ID NO. 145 in the absence of a transfecting agent (gymnotic transfection). The oligonucleotides were added to the cells for 2 days, after which oligonucleotide containing incubation medium was changed, and further incubation for 2 days was carried out. Expression of TGF-beta3 mRNA (see FIG. 13) was then measured and normalized to HPRT1 (Hypoxanthin-Phosphoribosyl-Transferase1). Under gymnotic transfection experimental conditions, the triple reactive oligonucleotide ASPH09 significantly inhibits the expression of TGF-beta3 mRNA.

Example 10

Panc-1 cells were treated with 10 μM, 3.3 μM, 1.1 μM, 0.37 μM, and 0.12 μM of ASPH03, ASPH36, ASPH45, ASPH47, ASPH65, ASPH69, ASPH71, ASPH80, ASPH115, ASPH 121, ASPH153, ASPH185, and ASPH189, respectively, in the absence of a transfecting agent (gymnotic transfection). The inhibitory effect of the modified oligonucleotides on expression of TGF-beta2 mRNA, was determined 72 h after treatment start. TGF-beta2 values were normalized to GAPDH and oligonucleotide concentrations resulting in 50% reduction of TGF-beta2 mRNA (=IC₅₀ values) were calculated. Under gymnotic transfection experimental conditions, the oligonucleotides enter the cells and strongly inhibit the expression of TGF-beta2 mRNA. The results of the experiments are shown in Table 4:

Name IC50 (μM) ASPH_065 0.37 ASPH_071 0.371 ASPH_115 0.6 ASPH_069 0.655 ASPH_047 0.78 ASPH_080 0.81 ASPH_153 0.9 ASPH_045 1.21 ASPH_121 1.27 ASPH_036 1.5 ASPH_185 3.05 ASPH_003 3.62 ASPH_189 4.26

All the modified oligonucleotides show an IC₅₀ in the low micromolar or even submicromolar range, showing that they have very high potency even without the requirement of a transfection reagent.

Example 11

Panc-1 cells were treated with 10 μM, 3.3 μM, 1.1 μM, 0.37 μM, and 0.12 μM of ASPH47, ASPH190, ASPH191, ASPH192, and ASPH193 in the absence of a transfecting agent (gymnotic transfection). The inhibitory effect of the modified oligonucleotides on expression of TGF-beta2 mRNA, was determined 72 h after treatment start. TGF-beta2 values were normalized to GAPDH and oligonucleotide concentrations resulting in 50% reduction of TGF-beta2 mRNA (=IC₅₀ values) were calculated. Under gymnotic transfection experimental conditions, the oligonucleotides enter the cells and strongly inhibit the expression of TGF-beta2 mRNA. The results of the experiments are shown in Table 5:

The inhibitory effect of the modified oligonucleotides on expression of TGF-beta1 and TGF-beta2 mRNA, respectively, was determined 72 h after treatment start. Significant reduction of the expression of TGF-beta1 mRNA is demonstrated in FIG. 17(a), FIG. 17(b), and FIG. 17(c). The dual TGF-beta1 and TGF-beta2 reactive oligonucleotides ASPH05 shows a significant reduction of the expression of both TGF-beta1 and TGF-beta2 mRNA, while the selective TGF-beta1 oligonucleotides significantly inhibit TGF-beta1 mRNA expression.

The expression of TGF-beta1 (black column), TGFßbeta2 (white column) and TGF-beta3 (striped column) mRNA was determined 24 h after transfection. Significant reduction of the expression of TGF-beta1 mRNA is demonstrated in FIG. 18(a), FIG. 18(b), and FIG. 18(c). The pan-specific TGF-beta1, TGF-beta2 and TGF-beta3 reactive oligonucleotides ASPH0009, ASPH1096, ASPH1131, and ASPH1132 show a significant reduction of the expression of all three isoformes, while the selective TGF-beta1 oligonucleotides significantly inhibit TGF-beta1 mRNA expression.

Example 17

Either Panc-1 cells (FIG. 19a (i), FIG. 19 a(ii), and FIG. 19a (iii)) or RenCa cells (FIG. 19b (i), FIG. 19 b(ii), and FIG. 19b (iii)) were treated with 3.3 μM of ASPH09, ASPH1047, ASPH1051, ASPH1059, ASPH1063, ASPH1064, ASPH1065, ASPH1066, ASPH1067, ASPH1068, ASPH1069, ASPH1070, ASPH1071, ASPH1072, ASPH1073, ASPH1074, ASPH1075, ASPH1076, ASPH1077, ASPH1078, ASPH1079, ASPH1080, ASPH1081, ASPH1082, ASPH1083, ASPH1084, ASPH1085, ASPH1086, ASPH1087, ASPH1088, ASPH1089, ASPH1090, ASPH1091, ASPH1092, ASPH1093, ASPH1094, ASPH1095, ASPH1097, ASPH1098, ASPH1099, ASPH1100, ASPH1101, ASPH1102, ASPH1103, ASPH1104, ASPH1105, ASPH1106, ASPH1107, ASPH1108, ASPH1109, ASPH1110, ASPH1111, ASPH1112, ASPH1113, ASPH114, ASPH1115, ASPH1116, ASPH1117, ASPH1118, ASPH1119, ASPH1120, ASPH1121, ASPH1122, ASPH1123, ASPH1124, ASPH1125, ASPH1126, ASPH1127, ASPH1128, ASPH1129, ASPH1130, ASPH1131, and ASPH1132, respectively, or the positive control ASPH1047 in the absence of a transfecting agent (gymnotic transfection or gymnotic delivery). The expression of TGF-beta1 (black column), TGF-beta2 (white column) and TGF-beta3 (striped column) mRNA was determined 72 h after transfection. Significant reduction of the expression of TGF-beta1 mRNA is demonstrated in FIG. 18(a), FIG. 18(b), and FIG. 18(c). The pan-specific TGF-beta1, TGF-beta2 and TGF-beta3 reactive oligonucleotides ASPH09, ASPH1096, ASPH1131, and ASPH1132 show a significant reduction of the expression of all three isoforms, while the selective TGF-beta1 oligonucleotides significantly inhibit TGF-beta1 mRNA expression.

Example 18

Mice bearing subcutaneous human pancreatic carcinoma Panc-1 tumors were treated with 1, 3, 10, and 30 mg/kg of ASPH47 under various treatment schedules: Q1Dx1-d6 (single SC injection, termination 5 days later), Q1Dx5-d6 (daily SC injection for 5 days, termination 24 hours later), and Q1Dx5-d10 (daily SC injection for 5 days, termination 5 days later). There was a dose dependent down-regulation of TGF-beta 2 mRNA in the kidney of these animals. TGF-beta 2 down-regulation was persistent up to 5 days after the last treatment with ASPH47, even after only single administration. TGF-beta 2 expression was detected by bDNA assay (branched DNA assay, which is a sandwich nucleic acid hybridization method that uses bDNA molecules to amplify signal from captured target RNA) and normalized to GAPDH. As shown in FIG. 23, data—representing TGF-beta2 to GAPDH mRNA ratio—are shown as a box plot in which median values and min. and max. values are presented (data expressed as n=10, except n=9 for vehicle and 3 mg/kg Q1Dx1 d6 groups).

Example 19

Mice bearing subsutaneous human pancreatic carcinoma Panc-1 tumors on both left and right flanks were treated with a daily injection of 1, 5, 15 or 50 mg/kg oligonucleotides for five consecutive days. The tumors were collected 24 hours after the last treatment and snap frozen. TGF-beta mRNA expression in tumors was detected by bDNA assay. Data—representing TGF-beta2 to GAPDH mRNA ratio—are shown as a box plot in which median values and min. and max. values are presented (data expressed as n=5). TGF-beta2 mRNA was down-regulated in tumors treated with various oligonucleotides (FIG. 24). There was no significant TGF-beta1 mRNA down-regulation in those groups (data not shown).

Example 20

Mice bearing subcutaneous human renal cell carcinoma 786-O tumors on both left and right flanks were treated with a daily injection of 50 mg/kg oligonucleotides for five consecutive days. The tumors were collected 24 hours after the last treatment and snap frozen. TGF-beta mRNA expression in tumors was detected by bDNA assay. There was significant down-regulation of TGF-beta2 mRNA in tumors treated with ASPH05, ASPH17, ASPH26, ASPH36, ASPH45, ASPH47, ASPH71, ASPH82, ASPH98, and ASPH105, respectively, (FIG. 25). Data—representing TGF-beta2 to GAPDH mRNA ratio—are shown as a box plot in which median values and min. and max. values are presented (data expressed as n=10, except for ASPH71 group n=9).

Example 21

Human Panc-1 cells were transfected with 20, 6.67, 2.22, 0.74, 0.25, 0.08 or 0.009 μM of the modified oligonucleotides ASPH47, ASPH1047, ASPH1106, ASPH1132, or ASPH47 in combination with ASPH1047; results are shown in FIGS. 26a to 26e ). Negative control is the scrambled oligonucleotide (scr LNA) of SEQ ID No. 145 (FIG. 26f ). All cells were transfected in the absence of a transfecting agent (gymnotic transfection or gymnotic delivery). The modified oligonucleotides were added to the cells for 3 days, which were incubated at 37° C. Thereafter the oligonucleotide containing medium was exchanged with fresh oligonucleotide containing medium and cells were incubated for further 4 days at 37° C. TGF-beta1 and TGF-beta2 protein levels in cell supernatants were determined by ELISA. ASPH47 specifically inhibits the expression of TGF-beta2 in a dose-dependent manner and does not have any target inhibiting effect on TGF-beta1 (FIG. 26a ). ASPH1047 specifically inhibits the expression of TGF-beta1 and does not have any target inhibiting effect on TGF-beta2 (FIG. 26b ), or only a slight TGF-beta2 inhibiting effect at higher concentrations. Also ASPH1106 inhibits TGF-beta1 expression in a dose dependent manner (FIG. 26c ). The multispecific ASPH 1132 shows a dose-dependent inhibition of the expression of TGF-beta1 and TGF-beta2 protein (FIG. 26d ). If ASPH47 and ASPH1047 are combined, the expression of both, TGF-beta1 and TGF-beta2 protein is inhibited in a dose-dependent manner (FIG. 26e ). The scrLNA of SEQ ID No. 145 does not show any inhibiting effect on the expression of neither TGF-beta1 nor TGF-beta2, even if the concentrations were doubled (40, 13.33, 4.44, 1.48, 0.49, 0.16, 0.05, or 0.02 μM) in comparison to the individual concentrations of ASPH47, ASPH1047, ASPH1106, or ASPH1132. Results for TGF-beta1 are indicated in diamonds, and results for TGF-beta2 in squares in FIGS. 26a to 26 f.

Example 22

Either Panc-1 cells (FIG. 27a (i), FIG. 27 a(ii), FIG. 27a (iii)) or RenCa cells (FIG. 27b (i), FIG. 27 b(ii), and FIG. 27b (iii)) were treated with 1.1 μM of ASPH190, ASPH191, ASPH192, ASPH193, ASPH194, ASPH195, ASPH196, ASPH197, ASPH198, ASPH199, ASPH200, ASPH201, ASPH202, ASPH203, ASPH204, ASPH205, ASPH206, ASPH207, ASPH208, ASPH209, ASPH210, ASPH211, ASPH212, ASPH213, ASPH214, ASPH215, ASPH216, ASPH217, ASPH218, ASPH219, ASPH220, ASPH221, ASPH222, and ASPH223, respectively, in the absence of a transfecting agent (gymnotic transfection or gymnotic delivery). The expression of TGF-beta1 (black column), TGF-beta2 (white column) and TGF-beta3 (striped column) mRNA was determined 72 h after transfection. Significant reduction of the expression of TGF-beta2 mRNA is demonstrated in FIG. 27a (i), FIG. 27 a(ii), FIGS. 27a (iii) and 27 b. The negative control is scrambled LNA (scr LNA) of SEQ ID No. 145.

Example 23

Panc-1 cells were treated with 10 μM, 3.3 μM, 1.1 μM, 0.37 μM, and 0.12 μM of ASPH47, M1-ASPH47, M2-ASPH47, M3-ASPH47, M4-ASPH47, M5-ASPH47, M6-ASPH47, M7-ASPH47, M8-ASPH47, M9-ASPH47, M10-ASPH47, M11-ASPH47, M12-ASPH47, M13-ASPH47, M14-ASPH47, or M15-ASPH47 in the absence of a transfecting agent (gymnotic transfection or gymnotic delivery). The inhibitory effect of the modified oligonucleotides on expression of TGF-beta2 mRNA, was determined 72 h after treatment start. TGF-beta2 values were normalized to GAPDH and oligonucleotide concentrations resulting in 50% reduction of TGF-beta2 mRNA (=IC₅₀ values) were calculated. Under gymnotic transfection experimental conditions, the oligonucleotides enter the cells and strongly inhibit the expression of TGF-beta2 mRNA. The results of the experiments are shown in Table 6:

oligos IC₅₀ (μM) M1_ASPH_0047 0.3 M2_ASPH_0047 0.49 M3_ASPH_0047 1.75 M4_ASPH_0047 0.95 M5_ASPH_0047 0.85 M6_ASPH_0047 1.49 M7_ASPH_0047 n.a. M8_ASPH_0047 0.89 M9_ASPH_0047 1.05 M10_ASPH_0047 7.75 M11_ASPH_0047 n.a. M12_ASPH_0047 1.58 M13_ASPH_0047 1.91 M14_ASPH_0047 n.a. M15_ASPH_0047 n.a. ASPH_0047 0.348

Most of the modified oligonucleotides show an IC₅₀ in the submicromolar to lower submicromolar range, showing that they have extremely high potency even without the requirement of a transfection reagent.

Example 24

Human Panc-1 pancreatic cancer cells (FIG. 28a ) or mouse RenCa renal cell carcinoma cells (FIG. 28b (i), and FIG. 28b (ii)) were treated with 3.3 μM of ASPH0009, ASPH1132, ASPH2000, ASPH2001, ASPH2002, ASPH2003, ASPH2004, ASPH2005, ASPH2006, ASPH2007, ASPH2009, ASPH2010, ASPH2012, ASPH2013, ASPH2014 ASPH2015, ASPH2016, ASPH2017, ASPH2018, ASPH2019, ASPH2020, ASPH2021, ASPH2023, ASPH2024, ASPH2025, ASPH23026, ASPH2027, ASPH2028, ASPH2029, ASPH2030, ASPH2031, ASPH2032, ASPH2033, ASPH2034, ASPH2035, ASPH2036, ASPH2037, ASPH2038, ASPH2039, ASPH2040, ASPH2041, ASPH2043, ASPH2044, ASPH2045, ASPH2046, ASPH2047, ASPH2048, ASPH2049, ASPH2050, ASPH2052, ASPH2053, ASPH2054, ASPH2055, ASPH2056, ASPH2057, ASPH2060, ASPH2061, ASPH2062, ASPH2063, ASPH2064, ASPH2065, or ASPH2066 in the absence of a transfecting agent (gymnotic transfection or gymnotic delivery). The expression of TGF-beta1 (black column), TGF-beta2 (white column) and TGF-beta3 (striped column) mRNA was determined 72 h after transfection. Significant reduction of the expression of TGF-beta3 mRNA is shown in FIG. 28a (i), FIG. 28a (ii), FIGS. 28a (iii) and 28 b. As anticipated from the sequences, the TGF-beta1, -beta2 and -beta3 reactive oligonucleotide ASPH_0009 (pan-selective) and ASPH_1132 that has 100% homology to mRNAs of human TGF-beta1 and -beta3 but has a mismatch to TGF-beta2 show significant reduction of the expression of all three isoforms. The selective TGF-beta3 oligonucleotides only significantly inhibit TGF-beta3 mRNA expression.

Example 25

Human A172 glioma cells were treated for 24 h with 10 nM (in the presence of a transfecting agent), of ASPH0009, ASPH1132, ASPH2000, ASPH2001, ASPH2002, ASPH2003, ASPH2004, ASPH2006, ASPH2007, ASPH2008, ASPH2009, ASPH2010, ASPH2011, ASPH2012, ASPH2013, ASPH2014, ASPH2016, ASPH2017, ASPH2018, ASPH2020, ASPH2021, ASPH2022, ASPH2023, ASPH2024, ASPH2025, ASPH2026, ASPH2027, ASPH2028, ASPH2029, ASPH2030, ASPH2031, ASPH2032, ASPH2033, ASPH2034, ASPH2035, ASPH2036, ASPH2037, ASPH2038, ASPH2039, ASPH2040, ASPH2041, ASPH2042, ASPH2043, ASPH2044, ASPH2045, ASPH2047, ASPH2049, ASPH2050, ASPH2051, ASPH2052, ASPH2053, ASPH2054, ASPH2056, ASPH2057, ASPH2058, ASPH2059, ASPH2060, ASPH2061, ASPH2062, ASPH2063, or ASPH2066. The expression of TGF-beta1 (black column), TGF-beta2 (white column) and TGF-beta3 (striped column) mRNA was then determined from cell extracts by bDNA assay. Significant reduction of the expression of TGF-beta3 mRNA is shown in FIG. 29(a), FIG. 29b (i) and FIG. 29b (ii). As anticipated from the sequences, the TGF-beta1, -beta2 and -beta3 reactive oligonucleotide) ASPH_0009 (pan-selective) and ASPH_1132 that has 100% homology to mRNAs of human TGF-beta1 and -beta3 but has a mismatch to TGF-beta2 show significant reduction of the expression of all three isoforms. The selective TGF-beta3 oligonucleotides only significantly inhibit TGF-beta3 mRNA expression.

Example 26: Target mRNA Downregulation in Rabbit Cells

Sequences of selected oligonucleotides were aligned with rabbit mRNA sequences of TGF-beta1 and 2. ASPH_0036 (TGF-beta2 selective antisense oligonucleotide, based on human mRNA sequence) showed 100% homology with rabbit TGF-beta2 mRNA, while ASPH_1059 (TGF-beta1 selective antisense oligonucleotide, based on human mRNA sequence) showed 100% homology with rabbit TGF-beta1 mRNA.

Rabbit Rab-9 skin fibroblasts were treated with 5 nM or 20 nM of either ASPH_0036 and ASPH_1059 in the presence of a transfecting agent for 24 hr. The expression of TGF-beta1 and TGF-beta2 mRNA was then determined in cell extracts by bDNA assay. Significant reduction of the expression of TGF-beta1 mRNA (51 and 77% at 5 and 20 nM, respectively) was achieved with ASPH_1059. Significant reduction of TGF-beta2 mRNA (79 and 80% at 5 and 20 nM, respectively) was achieved with ASPH_0036.

Example 27: Tissue Biodistribution and Target mRNA Downregulation Following Systemic Administration of ASPH_0047 in Balb/c Mice

Balb/C mice were treated with a single subcutaneous injection of ASPH_0047 (formulated in sterile physiological saline) at 5, 20 and 50 mg/kg animal body weight. Plasma and tissues were collected at the indicated times (from 3 individual animals), immediately snap-frozen and stored at −80° C. until analysis with an AEX-HPLC method (plasma/tissue PK) or for measurement of TGF-□2 and GAPDH mRNAlevels by bDNA assay. TGF-□2 mRNA levels were expressed relative to GAPDH mRNA expression level in corresponding samples.

The data depict that a single subcutaneous bolus administration of 50 mg/kg ASPH_0047 resulted in rapid transfer of the drug from subcutaneous to circulating blood compartments (T_(MAX) of ˜5-30 min), biphasic pharmacokinetic profile in plasma, with rapid initial elimination phase (within the first 24 hrs), followed by long terminal half-life (FIG. 30a ). It is further demonstrated that a marked long-lasting accumulation of the drug in various selected tissues. The major target organ (highest exposure/C_(MAX)) is the kidney, then the liver, skin and spleen, and lowest in the brain (data not shown). As also depicted in FIG. 30b , ASPH_0047 remained in the kidney tissue with pharmacological relevant doses (˜50 μg/gr, equivalent to 10 μM) from 24 h and for up to 14 days, with consequent long-lasting and marked suppression of TGF-β2 mRNA expression in the kidney tissue, with effective ˜80% target mRNA downregulation observed for at least 14 days.

Example 28

Immunodeficient mice were injected subcutaneously with human 786-O renal cell carcinoma cells (FIG. 31A), pancreatic Pancl cancer cells (FIG. 31B, C), or mouse SMA-560 glioma cells (FIG. 31D). When subcutaneous tumors reached the size of 100-300 mm³ (established tumors), animals were treated subcutaneously, Q1Dx5, with saline (Mock), control oligonucleotide (Control; 50 mg/kg), inactive oligonucleotides in this context (e.g., ASPH_0065 and ASPH_0071; 50 mg/kg) or ASPH_0047 at 50 mg/kg, or the indicated doses. Tumors (FIG. 31A-D) and kidneys (FIG. 31E-F) were collected 24 hr after the last administration. Tumors/kidneys were then further processed for determination of TGF-□2 and GAPDH mRNA levels by bDNA assay. In these experiments, control oligonucleotide was a 18-mer, 3+3 LNA gapmer scrambled sequence. Results are expressed as TGF-beta2/GAPDH mRNA ratio, and each individual tested sample is represented with median values indicated as red line. Under described experimental conditions (schedule and route of administration), systemic repeated administrations of ASPH_0047 in Balb/c mice led to a sequence-specific downregulation of TGF-beta 2 mRNA in established subcutaneous tumors and kidneys.

Example 29

Balb/c mice were injected with mouse Renca cells into renal subcapsule (FIG. 32A, B) or i.v. (FIG. 32C, D) on Day 0. Systemic treatment with vehicle or indicated oligonucleotides started on Day 7 (FIG. 32A; 50 mg/kg, s.c., twice weekly), on Day 1 (FIG. 32B; 12.5 mg/kg, s.c., twice weekly) for two consecutive weeks, or on Day 7 (FIGS. 32C and 32D; indicated doses, s.c., twice weekly) for 26-27 days. Number of lung metastasis was macroscopically evaluated, and level of lung metastasis was determined by either number of metastasis (FIG. 32A, C) or based on lung weight (FIG. 32B, D). Results are represented as box plot; with median values, upper and lower quartiles, and 90th and 10th percentiles. Under described experimental designs, Balb/c mice treated with ASPH_0047 showed a reduced number of lung metastasis or reduced lung weight (lung weight correlates to extent of lung metastasis) in mouse Renca RCC models.

Example 30

Human Panc-1 pancreatic cancer cells were treated with 3.3 μM of the indicated oligonucleotides in the absence of transfecting agent (gymnotic transfection or gymnotic delivery). The expression of TGF-beta1 (black column), TGF-beta2 (white column) and TGF-beta3 (striped column) mRNA was determined 72 h after transfection. Significant reduction of the expression of TGF-beta1 mRNA is shown in FIG. 32. The selective TGF-beta1 oligonucleotides only significantly inhibit TGF-beta1 mRNA expression while the control oligonucleotide LNA-scr does not affect expression of any TGF-beta isoform.

Example 31

Balb/c mice were injected with mouse 4T1 cells into mammary fat pad on Day 0. Systemic treatment with saline (Mock), pan-TGF-beta antibody (1D11), control oligonucleotide (LNA-scr), or ASPH_0047 started on Day 3 (30 mg/kg, s.c., twice weekly) and continued until D28, when animals were sacrificed. Number of lung metastasis was macroscopically evaluated, and level of lung metastasis was determined by either number of metastasis (left panel) or based on lung weight (right panel). Under described experimental design, treatment with ASPH_0047 reduced metastasis to the lungs, whereas the positive control, monoclonal TGF-beta antibody 1D11 had no effect on pulmonary metastasis in this model.

Example 32

CB17 SCID or Balb/c nude mice (n=3-5, except ASPH_0018 n=1 and ASPH_0037 n=2) were treated with 14-15 mg/kg of indicated LNA-modified oligonucleotides for four or five consecutive days (Q1Dx4-5). Plasma was collected 24 h after the last treatment and ALT levels were determined in plasma. Results are expressed as median values. Under this experimental condition, only 6/48 (12.5%) of tested oligonucleotides induced marked increase in plasma ALT (>300 units/1) indicating liver toxicity. The following Table 7 shows liver toxicity of systemically administered LNA-modified oligonucleotides:
